Step-by-step explanation:
Identify the slope and y-intercept of each of the following lines. Then graph each line.
y + 3 = 2 (x + 4)
Answer:
Below!
Step-by-step explanation:
1. Determining the y-intercept of the line:
The provided equation is in point slope form. To determine the slope and the y-intercept, we need to convert the equation to slope intercept form. Once it is converted to slope intercept form, the constant will be the y-intercept of the line. Start out by simplifying the distributive property on the R.H.S.
[tex]\implies y + 3 = 2 (x + 4)[/tex]
[tex]\implies y + 3 = (2x + 8)[/tex]
Now, open the parenthesis on the R.H.S
[tex]\implies y + 3 = 2x + 8[/tex]
If we take a look at the formula of slope intercept form (y = mx + b), we can see that "y" is isolated on the L.H.S. Thus, we need to subtract 3 both sides to isolate the y-variable.
[tex]\implies y + 3 - 3 = 2x + 8 - 3[/tex]
[tex]\implies y = 2x + 5[/tex]
We can see that the only constant in the equation is 5.
Therefore, 5 is the y-intercept.
2. Determining the slope of the line:
To determine the slope of the line, let's compare the formula with the equation obtained.
[tex]\implies (y = 2x + 5) \ = \ (y = mx + b)[/tex]
Thus, we obtain the following:
y = y2 = m (Slope)x = x 5 = b (Y-intercept)Thus, 2 is the slope of the line.
3. Plotting the line on the coordinate plane:
To graph the line on a coordinate plane, plot the y-intercept on the graph. The y-intercept is ALWAYS plotted on the y-axis.
Thus, the y-intercept plotted on graph is (0, 5).
Furthermore, plot a second point on the graph to draw a straight line through those points.
Determining the second point of the line:
If the slope of the line is 2, it means that the run (x) is 1 and the rise (y) is 2. Thus, we can add 1 to the x-coordinate of the y-intercept and 2 to the y-coordinate of the y-intercept.
⇒ (0, 5) ⇒ x = 0; y = 5 ⇒ Second point: x = 0 + 1; y = 5 + 2⇒ Second point: x = 1; y = 7⇒ Second point: (1, 7)Then, plot these points on the coordinate plane. Keep in mind that plot the x coordinate first, then the y-coordinate next. Once the coordinates are plotted, draw a line from the x-coordinate and another line from the y-coordinate. Finally, use your ruler and draw a line that passes through those two points. Your obtained graph is the graph of the line.

I guessed the answer to this question and got it right with 1/18 out of pure luck. I have no idea why it is 1/18! I'd love a quick explanation :D
Answer:
Step-by-step explanation:
If the first cube lands on a 4, then the second cube must land on 4 5 or 6.
It cannot land on 5 because that would make it the sum odd. (4 + 5 = 9)
So that leaves 4 and 6. You cannot use 2 because 4 + 2 = 6. The sum must be greater than 6.
So we are left with 2 results. The second cube should be 4 or 6
The results are 4 and 4
and 4 and 6

what is the end behavior of the function?
The end behavior of the function f(x) describes the behavior of the function as x approaches the +∞ f(x) approaches to 1/2 and the x approaches the -∞ f(x) approaches to 1/2.
What is a function?It is defined as a special type of relationship and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
[tex]\rm f(x) = \dfrac{4x-7}{8x+8}[/tex]
For the end behavior:
As x → ∞ f(x) → 1/2
And x → -∞ f(x) → 1/2
Thus, the end behavior of the function f(x) describes the behavior of the function as x approaches the +∞ f(x) approaches to 1/2 and the x approaches the -∞ f(x) approaches to 1/2.

the first term in this number pattern is 7.
7,12,10,15,13,..
what is the eighth term in this pattern
Answer:
21
Step-by-step explanation:
The pattern goes +5 , -2
From 7 you add 5, and than from 12 you minus 2. If you keep this up you get the following numbers.
7,12,10,15,13,18,16,21,19,24,22,27,25,30...ect
21 is the 8th term in the patterns so thats your answer.
The eighth term in the given number pattern is 21. This is obtained by the logic, of adding 5 and subtracting 2.
Number pattern:These keep a relationship between a series of numbers. That relationship is given by logic.
Some of the examples are like Even number pattern, Odd number pattern, Fibonacci series, etc.
Calculating the 8th term in the given pattern:Given that the number pattern is 7,12,10,15,13....
In this pattern 7 is the first term
So, the logic is adding 5 and subtracting 2
7+5=12 (2nd term)
12-2=10 (third term)
10+5=15 (fourth term)
15-2=13 (fifth term)
13+5=18 (sixth term)
18-2=16 (seventh term)
16+5=21 (eighth term)
Therefore, the eighth term is 21.

Step-by-step explanation:
First off, great job on answering the rest! Kevin worked the fastest because he has the lowest time spent per flyer. This means that for every flyer he spent time working on, he would complete it faster than Bill or Dante. This can also be estimated from the table given because although kevin only made 6, he spent only 24 minutes while Bill spent 56 minutes and only made 8. The smaller minutes spent in comparison to the amount of flyers made shows that Kevin is the fastest.

Which statement is BEST supported by the box plots?
A
The grocery expense for the category of "0-2 Children" is more spread out than the other category. This is most likely due to the median being much lower for the "0-2 Children" category than for the other category.
B
The grocery expense for the category of "3 or More Children" is more spread out than the other category. This is most likely due to families in the "0-2 Children" category having more outlier results.
C
The grocery expense for the category of "0-2 Children" is more spread out than the other category. This is most likely due to the minimum and maximum being closer together in the "0-2 Children" category.
D
The grocery expense for the category of "3 or More Children" is more spread out than the other category. This is most likely due to families in the "3 or More Children category" having more outlier results.

If the numbers of interest are 'a' and 'b', they will be zeros of the quadratic whose factored form is ...
(x -a)(x -b) = 0
Expanding that, we find an opportunity to use the given sum and product numbers:
x² -(a+b)x +ab = 0
x² -(-4)x +5 = 0
Rewriting this in vertex form gives ...
(x² +4x +4) +1 = 0
(x +2)² +1 = 0
We can find the values of x by subtracting 1 and taking the square root.
(x +2)² = -1
x +2 = ±√(-1) = ±i
x = -2±i
